一、使用及场景

添加菜单栏

src\router\index.js

{
    path: '/shopping',
    component: Layout,
    redirect: '/shopping/itime',
    alwaysShow: true, // will always show the root menu
    name: 'shopping',
    meta: {
      title: '商品管理',
      icon: 'shopping'
    },
    children: [
      {
        path: 'item',
        component: () => import('@/views/shopping/itime'),
        name: 'Item',
        meta: {
          title: '商品管理'
        }
      },
      {
        path: 'classify',
        component: () => import('@/views/shopping/classify'),
        name: 'Classify',
        meta: {
          title: '分类管理'
          // if do not set roles, means: this page does not require permission
        }
      },
      {
        path: 'activity',
        component: () => import('@/views/shopping/activity'),
        name: 'Activity',
        meta: {
          title: '活动管理'
        }
      }
    ]
  },

添加代理

vue.config.js

'use strict'
const path = require('path')
const defaultSettings = require('./src/settings.js')

function resolve(dir) {
  return path.join(__dirname, dir)
}

const name = defaultSettings.title || 'vue Element Admin' // page title

// If your port is set to 80,
// use administrator privileges to execute the command line.
// For example, Mac: sudo npm run
// You can change the port by the following method:
// port = 9527 npm run dev OR npm run dev --port = 9527
const port = process.env.port || process.env.npm_config_port || 9527 // dev port

// All configuration item explanations can be find in https://cli.vuejs.org/config/
module.exports = {
  /**
   * You will need to set publicPath if you plan to deploy your site under a sub path,
   * for example GitHub Pages. If you plan to deploy your site to https://foo.github.io/bar/,
   * then publicPath should be set to "/bar/".
   * In most cases please use '/' !!!
   * Detail: https://cli.vuejs.org/config/#publicpath
   */
  publicPath: '/',
  outputDir: 'dist',
  assetsDir: 'static',
  lintOnSave: false,//process.env.NODE_ENV === 'development',
  productionSourceMap: false,
  devServer: {
    port: port,
    open: true,
    overlay: {
      warnings: false,
      errors: true
    },
    proxy: {
      '/api': {
        target:'http://localhost:8081/', // 你请求的第三方接口
        changeOrigin:true, // 在本地会创建一个虚拟服务端，然后发送请求的数据，并同时接收请 求的数据，这样服务端和服务端进行数据的交互就不会有跨域问题
        pathRewrite:{  // 路径重写，/api/customer/list          
          '^/api': '' // 替换target中的请求地址，也就是说以后你在请求 http://localhost:8081/api/customer/list这个地址的时候直接写成/api即可
        }
      }

    },
    before: require('./mock/mock-server.js')
  },
  configureWebpack: {
    // provide the app's title in webpack's name field, so that
    // it can be accessed in index.html to inject the correct title.

    resolve: {

        '@': resolve('src')

    }
  },
  chainWebpack(config) {

    config.plugin('preload').tap(() => [

        include: 'initial'
      }
    ])

    // when there are many pages, it will cause too many meaningless requests
    config.plugins.delete('prefetch')

    // set svg-sprite-loader
    config.module
      .rule('svg')
      .exclude.add(resolve('src/icons'))
      .end()
    config.module

      .use('svg-sprite-loader')
      .loader('svg-sprite-loader')
      .options({
        symbolId: 'icon-[name]'
      })
      .end()

    config
      .when(process.env.NODE_ENV !== 'development',
        config => {
          config
            .plugin('ScriptExtHtmlWebpackPlugin')
            .after('html')
            .use('script-ext-html-webpack-plugin', [{
            // `runtime` must same as runtimeChunk name. default is `runtime`
              inline: /runtime\..*\.js$/
            }])
            .end()
          config
            .optimization.splitChunks({
              chunks: 'all',
              cacheGroups: {
                libs: {
                  name: 'chunk-libs',

                  priority: 10,
                  chunks: 'initial' // only package third parties that are initially dependent
                },
                elementUI: {
                  name: 'chunk-elementUI', // split elementUI into a single package
                  priority: 20, // the weight needs to be larger than libs and app or it will be packaged into libs or app
                  test: /[\\/]node_modules[\\/]_?element-ui(.*)/ // in order to adapt to cnpm

                commons: {

                  minChunks: 3, //  minimum common number
                  priority: 5,
                  reuseExistingChunk: true
                }
              }
            })
          // https:// webpack.js.org/configuration/optimization/#optimizationruntimechunk
          config.optimization.runtimeChunk('single')
        }
      )
  }
}

添加环境

.env.development

# 自定义服务路径
VUE_APP_BASE_API_V2 = '/api'

坑

问题

java.io.EOFException: Unexpected EOF read on the socket
添加这里会出现问题 java.io.EOFException: Unexpected EOF read on the socket 是因为
mock数据消费的body数据引起的注释掉mock-server.js -->app.use(bodyParser.json()) 即可
